Abstract
The utility model relates to a spanner, which comprises a casing body, a motor and a main shaft. The utility model is characterized in that one end of the main shaft is provided with a polygonal nut sleeve opening which extends out of the front part of the casing body, and the other end is connected with an inertial impact block in the casing body. The motor is driven by a low-voltage dc power supply, and the inertial block is directly driven to stir by transmission and speed change of two stage gears. In addition, a torsion spring is also additionally arranged between the two stage gears and the inertial block on the main shaft. The electric spanner with the structure uses the low-voltage dc motor to drive the working main shaft to work by combination of the transmission and the speed change of the two stage gears and the torsion spring. Thus, the utility model has the advantages of low energy consumption, large torque, favorable work continuity and compact structure.
Description
The utility model relates to spanner, particularly a kind of spanner that drives with low-tension supply.
Along with automobile as the developing rapidly and serve as day by day popularizing of walking-replacing tool of transport service with it, for changing doughnut, provide convenient and labor-saving operation tool, more and more be that the automobile driver is required.Because the fault of tire, tire need in time to change, and change the work of tire at present, all finish by hand, and change a tire, need loosen, tighten screw to reach more than 8～10 times, it is time-consuming to require great effort.
The purpose of this utility model is to provide that a kind of volume is less, moment is big, can utilize existing power supply on the automobile to carry out the electric wrench of work, high efficiency.
The utility model is to realize like this, the utility model spanner, comprise housing, motor, main shaft, it is characterized in that the polygon nut running-on of main shaft one end tool stretches out the housing front portion, the other end has an inertia impact piece to join with it in housing, motor is driven by low-voltage dc power supply, and inertial mass directly drives stirring by the secondary gear transmission gear shift, also has additional a torque spring in addition between secondary gear on the main shaft and inertial mass.
This electric wrench with described structure, in adopting low voltage DC motor to form the work of two-in-one drive working-spindle by secondary gear transmission gear shift and torque spring, can utilize existing power work on the automobile, energy consumption is little, moment of torsion strengthens, and the work continuity is good, the efficient height, and compact conformation is easy to carry and operates.
The following drawings and embodiment will be described further technical characterictic of the present utility model:
Accompanying drawing is a generalized section of the present utility model.
The drawing label:
1........ main shaft working end.12....... motor.
2........ axle sleeve.13....... housing.
